Individual Throttle Bodies

[Benson]

One almost guaranteed benefit of ITBs is the improved throttle response.

Not only will it provide good throttle response, the mid range gains is unbeliveable. We gain close to 15-20kw midrange with just itb's over single throttle. Torque wins races not peak power

Well the R33/R32 Skyline GTR runs 6 individual throttle body? Also to add to that the Pulsar GTi-R runs ITB's. Both system are box.

So you info is incorrect.

Yeh thats correct

One of the advantages of the GTI-R SR20 over it's Sivia cousin was it's quad throttle set up. The GTR's had a similar set up as well, it had one big intake plenum but each intake had it's own port if that makes any sense.

Need to find a pic... hrm

you cannot run ITB on boosted applications. Otherwise you could not boost the car. ITB are an NA novelity

omg nobody can understand what im saying. ill simplify:

jessica alba with make up on>jessica alba without make up
300kw>250kw
full strength beer>light beer
sex without condom>sex with condom
turbo skyline>NA skyline

ergo,

ITB's+Vtec Killer Cams>ITB's + no head work

[trism]

vtec killers are ghey

defeats the entire purpose of having a b series. for the VTAK Y0000

but in all seriousness, ITBs with ITR or CTR cams would be very naice

but in all seriousness, ITBs with ITR or CTR cams would be very naice

Sure is...tried on it a stock b18c7 and midrange is just awesome

[Benson]

ITB's+Vtec Killer Cams>ITB's + no head work

Well of course a built head is better than a stock head + you need a hetic engine combo to support those vtec killer cams

what motor were these gains achieved on, B18C or B16A.
were there any other mods done to the motor to get these kind of results. 15-20kw midrange is a huge gain for just having ITB's only, how many Nm of torque did you gain.

[Benson]

You'll net more gains on a B18c7 than a B16a due to displacement

The motor has CTR piston, set of BC spec 3 cams, Spoolin Performance 4-2-1 headers and ECu +tune. We did 2 tunes, one on single and one on ITB's.

In comparison to both graphs, that was the difference midrange. With top end, the itb's lost 5kw to the single throttle, but the car drive so much better with the Itb's. The torque difference is awesome

[Frankie]

would it be worth puitting a bigger throttle body on a D-series

[4age8u]

4age 4throtle bodies are mad on a vtec

[nick_sixx]

when a turbo car runs itb's, it requires a plenum, which differs from an intake manifold because of its ability to support the itb's.

[trism]

thats true, but it still has better throttle response etc
